Planetary gearbox with 16:1 reduction and 800 N.m continuous torque
The GBX1600160701F is a Schneider Electric planetary gearbox with straight teeth, 160 mm outer diameter, and a 16:1 reduction ratio. It delivers 800 N.m continuous output torque at 100 rpm and 30 °C, with a maximum output torque of 1280 N.m under the same conditions. Rated for 30000 hours service life at 100 rpm and 30 °C, the gearbox is lubricated for life and requires no maintenance interval planning for most production cycles.
The 800 N.m continuous rating is the figure to size against your duty cycle — the 1280 N.m maximum is for peak loads only, not sustained operation. Torsional rigidity of 41 N.m/arcmin tells you how much the shaft twists under load; for a servo-driven indexing table, this stiffness keeps position error within the machine's repeatability budget. Maximum torsional backlash is 10 arc.min — this is the lost motion at the output when the input reverses. For positioning axes that reverse direction, this backlash figure determines whether the gearbox can hold the required accuracy without a secondary encoder. Efficiency is 94 % at rated load, meaning 6 % of input power is lost as heat. Noise level is 70 dB at 1 m, no-load — typical for a straight-tooth planetary of this size; helical or ground-tooth versions would run quieter but at higher cost.
Sourcing and lifecycle — obsolete, quoted to order
Available through independent surplus and broker channels. No pin-compatible or drop-in replacement is documented by Schneider — a functional replacement would require reviewing the mounting interface, shaft dimensions, and torque class.
Mechanical ratings — axial force, radial force, and sealing
Maximum axial force Fa is 6000 N at 100 rpm for the 30000-hour service life, or 8000 N for a 10000-hour life at 30 °C. Maximum radial force Fr is 4200 N at 100 rpm for 30000 hours, or 6000 N for 10000 hours, measured at mid-distance from the output shaft. Shaft output sealing is IP54 — protected against dust ingress and splashing water from any direction. The housing is black anodized aluminium; the shaft is C45 steel. Ambient temperature range for operation is -25 to 90 °C.
